Tactical Medic Light

I mean, any light source will amplify in NVG, right? The only reason I know of to use IR is that you need NVG to see it - ie, it should be safer when fighting an enemy with limited NVG resources.

It's important to differentiate Thermal/IR and NV viewers.

The military NVGs I've used, make use of very low light (e.g. starlight) and and amplify it, they do NOT make warm objects look brighter, the way Thermal Imaging or FLIR viewers do.

NVGs also respond in the IR range, so in total darkness the scene can be lit with IR which people cannot see, but warmer objects are not brighter.

LED involves a physics term: bandgap
the spectrum it gives out depends on this thing
For colored LED(like 5mm)
It have only 1 bandgap which gives only 1 type of wavelength of light,aka monochromic
Red =/= infrared
So that NVG(theres many type of NVG, light intensifying/passive infrared/active infrared etc.)
Might not be able to see red light, depends on which type he/she uses
If i was wrong, please point it out

LASER light is monochromatic - a narrow peak in a spectral graph, but LEDs are not monochromatic - they have quite a broad spectral curve.

A Red LED will put out some energy in the IR region and also the Orange region.

Some LEDs that peak in the IR region also put out light in the visible red.

What's the better light for a combat medic? I've seen my guys using green, blue and red.

Full-colour vision is wonderful to help us recognise so many things, that colour-filtered light makes difficult for us.

If you need full acuity of vision, you also have to have light bright enough to activate Photopic vision. Since our eyes are most sensitive at Green - in terms of absolute energy, you need less Green light than any other colour to achieve this.

Sorry for the post resurrection, but I came across a video from ADS and First-Light that shows their light using a mix of red and green to highlight blood:

Red light is useless for highlighting blood - under Red light, EVERYTHING of any colour is a shade of red.

Read it again, watch the video.

I have a Tomahawk MC, and I can tell you that it is an awesome light. By running the red and the green LEDs at the same time, you can get some pretty good color rendition.

Yeah, for those who couldn't be bothered viewing the video, the red and green combo of the tomahawk gives off a light which shows up everything as green, exept for things that are red, which show up as, well, red. Easier on the eyes than blue too.
